fullscreen is now managed (activation and deactivation) in skins2
 exactly as it is done in qt4.
    - activation when a VOUT_WINDOW_SETFULLSCREEN is received
    - deactivation when (and only when) a vout_window release is received.

This brings some useless overhead for native UTF-8 systems.
Linux packagers may want to define ASSUME_UTF8 to avoid this problem.

Also, this assumes that iconv_open() recognizes "" as the current

Move googleimage search first, and enable it again but don't use eg filename in search query.
Move musicbrainz after last.fm, and don't try more than one way to find art, also do query once in 2 sec

If you get bad hits from googleimage album-art, please report them to me.
